And as far as the post stating that in the west loyalty isnt followed as much and doesnt need to be is completely wrong. why study an art if you arn't going to follow it completely, and learn all aspects about it i am pretty sure that that is what the word BUDO entails as part of its tenants, and maybe one should look up the word BUSHIDO before making a statement of that kind.
So by virtue of your statement above, you consider your Sensei your Lord to whom you must remain loyal? The loyalty inherent in the code of Bushido is to your Lord. He is the one who feeds you, shelters you and your family (via the stipend you receive) in return for your service. Does this sound like the relationship you have with your Sensei?
